I'am the proud owner of an 1963 Catalina 4 door 389cui. I bought it last year here in Germany and I really love. Sometimes it's a little bit difficult to get spare partes here in Europe, or find a way to ship it to munich (greetings from Orktoberfest). Last experience was 200 USD for the cooler ==> 300 for shipping PLUS 130 for Taxes grmmmmmm. Have anybody an idea which Transmission oil I need for that car? AND how much? Is there a difference between the Super Hydra-Matic "315" and the Roto Hydra-Matic "10". I'am not really shure whioch transmission ist buildt in. Is there something where i can recognize that during driving? Sorry for that strange questions but sometime ist really hard to find some information here in Europe for that stuff. Hope my english is understandable. Thanks a lot for your help! With kind regard catalinajoe
